The Grateful Dead closed out their five-decade career over the holiday weekend with three sold-out Chicago shows. Now that the dust has settled, industry analysts have begun to review the weekend’s earnings. The estimated profit—no, not that estimated prophet—likely topped $55 million, Billboard reports.

Each successive night at Chicago’s Soldier Field broke the venue’s attendance record set by U2 in 2009. Approximately 212,000 attended the Chicago shows, and with average ticket prices at $120 that brings box office gross to $24.5 million. The 130,000 who turned out for the two warm-up shows in Santa Clara the prior weekend likely generated enough to bring total box office gross past $50 million.

According to Billboard, concertgoers spent an average of $25 on merchandise, which would add at least $5 million more to the mix. Numbers are still being calculated for the pay-per-view, movie theater, and home streaming events. The Grateful Dead will always release three different versions of the final Chicago shows in November, which will add even more revenue to the pot.
